It is finally done. It did not take too long and I really enjoyed tatting this. Tatted in Lizbeth Size 40 in Col. 633 Purple Dark, Col. 641 Lilac Dark, Col. 162 Purple Iris Fusion and Col. 646 Purple Iris Light (from centre out).
Margaret tatted the onion ring snowflake here and I really liked how she used a darker thread for the inner ring. I decided to try it myself. Tatted in Lizbeth Size 40 River Blue Medium Col. 708 and Ocean Turquoise Dark Col. 657 (top); Sea Island Citrus Col. 161 and Ocean Turquoise Dark Col. 657 (bottom). The pattern can be found on Georgia Seitz's online tatting class website here.
I used the same variegated thread Lizbeth Size 40 Purple Iris Fusion Col. 162 for Round 10. Now measuring about 14 inches across. One more round in this variegated thread before I switch colours again.
